Sick of stalled zippers? Here’s your fix: The MagZip from Under Armour automatically aligns and locks into place by a magnetic pull. Engineer/inventor Scott Peters-along with his mom, Nancy Peters, and friend Dave Lyndaker-developed the efficient sliding technology to help Nancy’s brother who suffers from Myotonic Dystrophy, which makes zippers and buttons extra tricky. “We would design a concept, get it built, hand assemble it ourselves, sew it into jackets and then test it on friends, family and Uncle Dave,” Peters says. “After many prototypes and a few years of development, we finally had something that worked great!” The device took top honors at Under Armour’s annual Future Show for inventors-and, starting this fall, will appear in more than 15 men’s, women’s and kids’ athletic items by UA, including this ColdGear Infrared Zenith hoodie ($175) in a “Russian Nights” print—perfect for a moonlight run. Also look for a stylish men’s version called the Werewolf. Howl!
